Probably one of the switches (or the memory card inside) is now broken after a lot of years.....
Check:
show stack topology
show ni
show cmm

Because the switches are still running - you will see the problem probably still after a power down and not with this commands.
With "show stack topology" and "show running-directory" you see the actual master (f.e. chassis 1).
With "ls" and "rls 2 /flash" you check the filesystem at both chassis.
you can use "fsck /flash" and "freespace" to check the flash.
Use "telnet 127.2.2.1" to connect to second NI and use the same commands there.

If the second NI is the problem you can try the following:
direct on NI2 (via telnet from NI1 or serial):
> newfs /flash
> mkdir certified
> mkdir working
(important - now no power down)
from NI1 you can copy the certified and working files to NI2:
-> rcp /flash/certified/Kbase.img 2:/certified/Kbase.img
-> rcp /flash/certified/Kos.img 2:/certified/Kos.img
...
